The theory and approach of three-dimensional geological modeling are complex and diverse,the application for the model have multi-scale character due to the different needs.In consideration of the basis features of semantics,geostatistics,mineral deposits and three-dimensional modeling process ,This dissertation provides a three-dimensional semantic-scale modeling concept and the theory of multiple sequences of three-dimensional models based on semantic . Taking the modeling of stratified and non-stratified geographical object as examples, the paper described the process of multiple sequences of three-dimensional models based on semantics.
